I have a Bluetooth module sitting on my desk that happens to use a CPU descended from OpenRISC - except it's 100% proprietary in both implementation and instruction set. I don't think there's even any public documentation of the instruction set. Basically, some of the OpenRISC folks decided there was more money in proprietary chips; they also blocked the merging of the gcc code upstream, which helped kill it off as a viable open architecture.
